YVILLIAM H. DAYTON, OF TORRINGTON, CONNECTICUT, ASSIGNOR TO THE EXCELSIOR NEEDLE COMPANY, OF SAME PLACE.

SWAGlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 548,431, dated October 22, 1895.

Application filed May 23, 1392. Serial No. 433,967. (No model.)

To ttZZ whom it may concern.-

Be itknown that I, \VILLIAM H. Dnrroma citizen of the United States, residing at Torrington, in the county of Litchfield and State of Connecticut, have invented an Improve ment in Swaging-Machines, of which the following is a specification.

Needles and other round articles have been swaged by the action of dies across a revolving shaft, which dies have been pressed to ward each other by the action of toggle-blocks, as shown in Letters Patent No. 341,558, and in other instances the outer ends of the transverse dies have been acted upon by rollers around within a circular shell, and in Letters Patent No. 474,548, granted to me May 10, 1892, a machine is represented in which there are wedges receiving an end movement during the swaging operation for bringing the dies nearer together or allowing them to open farther, thereby adapting the machine to the swaging of tapering articles or articles of varying diameters.

I make use of a pair of swaging-dies and means for closing said dies, such as toggleblocks and followers, and screws for setting up such followers more or less, and gears for rotating'all the screws simultaneously to allow the dies to open for passing in the wire or for moving the dies toward each other to reduce the wire to the desired extent.

In the drawings, Figure 1 is a longitudinal section representing the revolving shaft and the toggle-blocks and screws for simultaneously adjusting the followers for the toggleblocks, and Fig. 2 is an elevation of a portion of the machine shown in Fig. l.

The shaft A is supported in a suitable head B, and across the end of the shaft A is a transverse mortise receiving the dies C C, which may be held in position by any suitable device, such as a circular cap D, and this shaft A is revolved by competent power, such as a belt applied to the pulley E.

The support B for the shaft A is provided with a circular flange or shell B, and in the interior of this shell B there are radial slots for the reception of the followers F, to which are connected the toggle-b1ocks G, and these are held in place by a face-ring H connected to the shell B, and there are screws K passing through the shell B and acting upon the followers F, and there are springs to move the toggle-blocks back to their normal positions.

The parts thus far described correspond generally to those set forth in the aforesaid Patent No. 341,558, but in the said patent the screws K were employed for adjusting the parts to compensate wear, and no provision was made for adjusting the followers F simultaneously to allow for the dies C C being opened or closed more or less during the swag ing operation. To efiect this object the screws K are to be rotated simultaneously. 1 have represented pinions L upon the outer ends of the respective screws, and these pinions are acted upon by a toothed ring M, surrounding the stationary shell B, and this ring M can be rotated more or lessby any suitable means. I have represented a worm-pinion N acting upon the teeth of the said ring M, such worm-pinion being rotated by a suitable shaft and crank.

I remark that it is preferable to rotate the ring M by means independent of the pinions L; but if a square is provided at the end of either screw K, so as to rotate either pinion L by a suitable key or wrench, such pinion may be made use of in giving motion to the ring M and moving all the other screws simultaneously and in unison therewith. By the aforesaid means the followers of the toggle-blocks can be brought nearer to the axis of rotation or farther away therefrom, and in so doing the dies 0 can be brought closer together or allowed to open to a greater extent during the swaging operation. Hence the article that is being swaged can be drawn down to a uniform size or the diameter can be increased or lessened during the swaging operation, as may be desired.

In the drawings 1 have represented the dies as solid, the same as shown in my Patent No. 341,558; but the dies might be made in two parts with die-blocks or followers, as shown in my Patent No. 37 6,144.

I claim as my invention-- 1. In a swaging machine, the combination with the swaging dies and mechanism for actuating the dies to swage the wire, of mechanism for opening or moving apart the swaging dies and for closing or moving toward each other the swaging dies to sv'vage the wire, consisting of. adjusting screws provided with gears adapted to engage a gear, and said gear, mounted and adapted to rotate on the stationary part of the swaging machine, and provided with a gear surface meshing with and operated by a gear for moving the same, substantially as shown and described.

2. In a swaging machine, the combination with the swaging dies, and mechanism for actuating the dies to swage the wire, of mechanism for opening or moving apart the swaging dies, to allow the wire to pass between the same and for closing or moving toward each other the swaging dies to swage the Wire, consisting of adjusting screws provided with gears adapted to engage a gear, and said gear, mounted and adapted to rotate on a. stationary part of the swaging machine, and means for rotating said gear first in one direction and then in the other, substantially as setforth.

Signed by me this 18th day of May, 1892.
